Universal Studios Hollywood just added a new original haunted house to its Halloween Horror Nights 2026 lineup: Dead, Deader, Deadest, a graveyard nightmare set inside the fictional Deville Family Funeral Home.

It is the newest maze revealed for the event and the latest original, non-movie concept to join a lineup already packed with big horror names. Universal announced the house today.

What Is 'Dead, Deader, Deadest'?

The house centers on a fictional so-called miracle drug called Ambrotox, which promises to restore a dead body's features without the process of embalming. The problem is what happens when it fails.

When the drug backfires, a century's worth of corpses rise from their graves, dead set on terrorizing the living. Guests walk straight through the decaying halls of the Deville Family Funeral Home to face them.

Here is how Universal describes the house:

Ambrotox claims to restore the deceased's features without the process of embalming. But when the miracle drug backfires, a century's worth of corpses rise from their graves dead set on terrorizing the living. In this haunted house, stare death in its decaying face and unearth the dark secrets that lie within the Deville Family Funeral Home.

The Story So Far

Universal has kept the reveal short, but the announcement gives fans the core setup. Here is what we know about Dead, Deader, Deadest:

• The setting: the Deville Family Funeral Home, a decaying funeral home and graveyard.
• The hook: Ambrotox, a miracle drug that claims to restore the deceased without embalming.
• The twist: the drug backfires and a century's worth of corpses climb out of their graves.
• The threat: the reanimated dead are "dead set on terrorizing the living."
• The tone: guests "stare death in its decaying face" and "unearth the dark secrets" inside the funeral home.
• The type: an original house, not based on a movie or TV series.

How It Fits the 2026 Halloween Horror Nights Lineup

Dead, Deader, Deadest joins a growing slate of houses confirmed for Universal Studios Hollywood this year. So far the announced lineup includes:

• Dead, Deader, Deadest (original)
• Sinners, based on the award-winning horror film
• Stranger Things 5, based on the final season of the Netflix series
• Hellraiser, based on the original film trilogy with Pinhead and the Cenobites
• Evil Dead Burn, based on the new film

That makes Dead, Deader, Deadest one of the few fully original concepts in a lineup otherwise built on well-known movie and TV names. Universal has said more houses, scare zones, and shows will be revealed as the event gets closer.
